Spectral line — Continuous spectrum Emission line … Wikipedia
Spectral bands — are part of optical spectra of polyatomic systems, including condensed materials, large molecules etc. Each line corresponding to one level in atom splits in molecules. When the number of atoms is large, one gets continuum of energy levels, so… … Wikipedia
Emission spectrum — The emission spectrum of a chemical element or chemical compound is the spectrum of frequencies of electromagnetic radiation emitted by the element s atoms or the compound s molecules when they are returned to a lower energy state. Each element s … Wikipedia
Spectral linewidth — The spectral linewidth characterizes the width of a spectral line, such as in the electromagnetic emission spectrum of an atom, or the frequency spectrum of an acoustic or electronic system. For example, the emission of an atom usually has a very … Wikipedia
Emission spectroscopy — is a spectroscopic technique which examines the wavelengths of photons emitted by atoms or molecules during their transition from an excited state to a lower energy state. Each element emits a characteristic set of discrete wavelengths according… … Wikipedia
spectral line — n. any of a number of lines in a spectrum produced by the emission of electromagnetic radiation from an excited atom: a spectral line represents the energy difference between two energy levels … English World dictionary
spectral line — noun : one of a series of linear images of the narrow slit of a spectrograph or similar instrument corresponding to a component of the spectrum of the radiation emitted by a particular source * * * Optics. a line in a spectrum due to the… … Useful english dictionary
spectral series — /spɛktrəl ˈsɪəriz/ (say spektruhl searreez) noun a series of lines in the emission spectrum of a substance, each line representing a particular transition between energy levels of an atom of an element …
Atomic spectral line — In physics, atomic spectral lines are of two types: * An emission line is formed when an electron makes a transition from a particular discrete energy level of an atom, to a lower energy state, emitting a photon of a particular energy and… … Wikipedia
Fraunhofer lines — In physics and optics, the Fraunhofer lines are a set of spectral lines named for the German physicist Joseph von Fraunhofer (1787–1826). The lines were originally observed as dark features (absorption lines) in the optical spectrum of the… … Wikipedia
Hydrogen spectral series — In physics, the spectral lines of hydrogen correspond to particular jumps of the electron between energy levels. The simplest model of the hydrogen atom is given by the Bohr model. When an electron jumps from a higher energy to a lower, a photon… … Wikipedia
